Description

Technical Field

[0001] The utility model relates to the technical field of compound fertilizer production, in particular to a mixing device for compound fertilizer production. Background Art

[0002] Compound fertilizer refers to fertilizer containing two or more of the three nutrient elements of nitrogen, potassium and phosphorus. The production of compound fertilizer is divided into two processes: physical mixing and chemical reaction mixing. The traditional physical mixing process usually uses a mixing device to mix and stir the prepared single nutrient element fertilizers together to produce compound fertilizer. However, the existing compound fertilizer mixing device has the following disadvantages when used:

[0003] Existing compound fertilizer mixing devices are generally horizontal, with an open top and a spiral ribbon inside. A motor is used to drive the spiral ribbon to rotate to achieve compound fertilizer mixing. However, when this mixing device is used, several compound fertilizers are poured into the device at one time and then stirred by the spiral ribbon. This stirring method is relatively inefficient and difficult to fully mix in a short time. Secondly, if the mixed fertilizer has a certain humidity, the fertilizer is easy to adhere to the spiral ribbon and the inner wall of the device, making it difficult to clean. Therefore, the utility model proposes a mixing device for compound fertilizer production. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, it relates to a mixing device for compound fertilizer production, including a support plate 1, a plurality of support rods 2 are fixed on the lower surface of the support plate 1, a mixing barrel 3 is penetrated and fixed in the middle of the support plate 1, and the bottom end of the mixing barrel 3 is inverted cone shape, and a feeding port 11 is provided at the bottom of the mixing barrel 3, two electric telescopic rods 4 are fixed on both sides of the upper surface of the support plate 1, the telescopic ends of the two electric telescopic rods 4 are fixedly connected with a top cover 5, a stirring assembly is provided on the lower surface of the top cover 5, a motor 6 for driving the stirring assembly to rotate is fixed in the middle of the upper surface of the top cover 5, a feed hopper 12 is fixedly connected to the upper surface of the side of the top cover 5, and a material dividing assembly is installed on the lower surface of the top cover 5 near the feed hopper 12.

[0023] like Figure 2 As shown, the stirring assembly includes a vertical shaft 7, the top end of the vertical shaft 7 is fixedly connected to the output shaft of the motor 6, and a spiral belt 8 is fixed on the surface of the vertical shaft 7.

[0024] When the motor 6 drives the vertical shaft 7 to rotate, the spiral ribbon 8 on the surface of the vertical shaft 7 will rotate inside the mixing barrel 3, and the spiral ribbon 8 can be used to stir and mix the fertilizer in the mixing barrel 3.

[0025] like Figure 2 As shown, the bottom surface of the vertical shaft 7 is rotatably connected to a sleeve 9 via a bearing, and the bottom end of the sleeve 9 is fixedly connected to a bottom cover 10, the size of the bottom cover 10 is larger than the size of the feed opening 11, and the bottom cover 10 is a curved surface structure.

[0026] When the top cover 5 is closed on the top of the mixing drum 3, the vertical shaft 7 and the bottom cover 10 are both located inside the mixing drum 3, and the side of the bottom cover 10 is in contact with the inverted conical inner wall at the bottom of the mixing drum 3, so that the bottom of the mixing drum 3 is closed. When the top cover 5 is raised, the bottom cover 10 is away from the discharge port 11, and the fertilizer can be discharged from the discharge port 11. In addition, due to the shaft sleeve 9, after the bottom cover 10 is in contact with the inner wall of the mixing drum 3, the bottom cover 10 will not affect the rotation of the vertical shaft 7.

[0027] like Figure 1-Figure 3 As shown, the material dividing assembly includes a side shaft 13 rotatably connected to the lower surface of the top cover 5, a driven gear 14 is fixed to the top surface of the side shaft 13, a plurality of material dividing plates 15 are fixed to the bottom surface of the side shaft 13, and the material dividing plates 15 are located below the feed hopper 12, a driving gear 16 is fixed to the middle of the output shaft of the motor 6, and the driving gear 16 is meshed with the driven gear 14.

[0028] When the motor 6 rotates, the driving gear 16 will drive the driven gear 14 and the side shaft 13 to rotate, so that the dividing plate 15 at the bottom of the side shaft 13 rotates, and the fertilizer falling from the feed hopper 12 will be scattered by the dividing plate 15 to various places inside the mixing barrel 3, achieving the premixing effect and shortening the time for the screw belt 8 to mix the fertilizer.

[0029] like Figure 2 and Figure 3 As shown, the size of the driving gear 16 is larger than that of the driven gear 14. By driving the small gear to rotate through the large gear, the rotation speed of the side shaft 13 and the dividing plate 15 can be increased.

[0030] like Figure 2 and Figure 4 As shown, shielding covers 17 are rotatably connected to both sides of the top of the feed hopper 12 through hinges, and the lower surface of the shielding cover 17 and the inner wall of the feed hopper 12 are fixedly connected with a spring 18.

[0031] The shielding cover 17 can be rotated downward. When fertilizer is poured into the feed hopper 12, the fertilizer presses down the shielding cover 17 to rotate downward. After the fertilizer is added, under the elastic force of the spring 18, the shielding cover 17 rotates upward and resets to prevent the fertilizer from splashing out of the feed hopper 12.

[0032] Working principle: Start the motor 6 to drive the spiral belt 8 and the multiple dividing plates 15 at the bottom of the side shaft 13 to rotate, and then add a variety of fertilizers from the feed hopper 12 to the inside of the mixing barrel 3. During the adding process, the dividing plates 15 will scatter the fertilizers to various places inside the mixing barrel 3. At the same time, the spiral belt 8 will stir and mix the fertilizers entering the mixing barrel 3. After the mixing is completed, start the electric telescopic rod 4 to drive the top cover 5 to rise. At this time, the bottom cover 10 is separated from the discharge port 11, and the fertilizer is directly discharged from the discharge port 11. If the mixed fertilizer is wet, the surface of the spiral belt 8 and the inner wall of the mixing barrel 3 are adhered with fertilizers. At this time, the surface of the spiral belt 8 and the inner wall of the mixing barrel 3 can be cleaned.
